The text suggests we may be entering a fifth social revolution based on which development?

• A. Mapping the human genome and biotechnology
• B. Global trade networks
• C. Urban architectural styles
• D. Traditional family roles

Answer: (A)

The main idea being tested is that a new era of social revolution could be driven by breakthroughs in biology, especially mapping the human genome and biotechnology. This development marks a qualitative shift because it gives society the ability to read, edit, and redesign living systems, spawning new industries, medical approaches, and governance challenges that can transform power dynamics, labor, and everyday life. Like previous revolutions, the driver is a transformative technology that changes what counts as knowledge, how value is produced, and how institutions function. Global trade networks describe ongoing globalization rather than signaling a new, biology-centered upheaval, and urban architectural styles or traditional family roles reflect social change in other ways that don’t capture this biotech-driven shift. So, mapping the genome and advancing biotechnology best signals the potential for a fifth social revolution.
